On August 5, 2013, pursuant to the Agreement and Plan of Merger, dated May 24, 2013 (as amended, the “Merger Agreement”), among Valeant Pharmaceuticals International, a Delaware corporation (“VPI”), Stratos Merger Corp., a Delaware corporation and wholly owned subsidiary of VPI (“Merger Sub”), Bausch & Lomb Holdings Incorporated, a Delaware corporation (“B&L”) and, with respect to limited provisions of the Merger Agreement, Valeant Pharmaceuticals International, Inc., a corporation organized under the laws of Canada and the ultimate parent of VPI (“Valeant”), Merger Sub merged with and into B&L, with B&L continuing as the surviving entity and wholly owned subsidiary of VPI (the “Merger”). B&L is a leading global eye health company.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, at the effective time of the Merger (the “Effective Time”), each share of B&L common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time was converted into the right to receive its pro rata share (the “Per Share Merger Consideration”), without interest, of an aggregate purchase price equal to $8,700,000,000 minus B&L’s existing indebtedness obligations, minus certain of B&L’s transaction expenses, minus certain payments with respect to certain canceled B&L performance-based options (which were not outstanding immediately prior to the Effective Time), plus the aggregate exercise price applicable to B&L’s outstanding options immediately prior to the Effective Time, and plus certain cash amounts, all as further described in the Merger Agreement.

Each B&L restricted share and stock option, whether vested or unvested, that was outstanding immediately prior to the Effective Time was canceled and converted into the right to receive the Per Share Merger Consideration in the case of restricted shares or, in the case of stock options, the excess, if any, of the Per Share Merger Consideration over the exercise price of such stock option.

As previously disclosed, part of the Merger consideration was funded by $850,000,000 of a new series of tranche A term loans and $3,200,000,000 of a new series of tranche B term loans under Valeant’s Third Amended and Restated Credit and Guaranty Agreement (the “Credit Agreement”), dated February 13, 2012, by and among Valeant, certain of its subsidiaries, including VPI, as guarantors, a syndicate of financial institutions and investors, Goldman Sachs Lending Partners LLC (“GSLP”), J.P. Morgan Securities LLC (“JPM”) and Morgan Stanley Senior Funding, Inc. (“MS”), as Joint Lead Arrangers and Joint Bookrunners, JPMorgan Chase Bank, N.A. (“JPMCB”) and MS, as Co-Syndication Agents, JPMCB, as Issuing Bank, GSLP, as Administrative Agent and Collateral Agent, and the other agents party thereto.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto.

On August 7, 2013, the board of directors of Valeant (the “Board”) appointed Fred Hassan as a director, to serve on the Board until Valeant’s next meeting of shareholders at which directors are elected. As previously announced, Mr. Hassan, who is the former chairman of the B&L board, was expected to join the Board after the Merger closed. Mr. Hassan will be paid in accordance with the current compensation approved by the Board for directors, which currently provides for an annual grant of restricted stock units with a fair market value of $375,000, an annual retainer in the amount of $75,000 and additional compensation based on his Board committee membership.

On August 6, 2013, Valeant issued a press release announcing the completion of the Merger. A copy of the press release is being filed herewith as Exhibit 99.1 and the information therein is incorporated by reference into this Current Report on Form 8-K.
